All that you wanted to know about the rendering process

Wall rendering refers to the process of protecting the external walls of your home by applying a coating made up of plaster or any other material. There are quite a variety of materials which can be used as render to coat the walls. The final decision has to be the home owners. When you visit a professional renderer in Sydney they will give you advice on the best possible rendering material for your home.

Rendering and plastering are two different processes

The major difference between rendering and plastering is that where plaster is used to line the interior wall, rendering is a process which deals exclusively with the exterior surface of the walls. Render is composed of cement, sand and water. Lime is usually added to the mixture to make it stronger. Also the proportion of material sued to make render and plaster is vastly different. The following are a few major differences between the two.

Render is made with more cement and has a great deal of sand added to it as well. This helps increase the strength of the wall. This offers protection against the elements like rain, snow and any extreme weather conditions.

While plaster makes use of a great deal less cement, also only fine sand is added to the mixture. This makes for a smoother mixture. This help attain a texture which can be used to line the inner walls and give them a sooth ad glossy finish.

The Rendering process explained

First the surface of the walls are prepared for rendering in Sydney. Water is used to clan the walls thoroughly to get rid of all the dirt and debris. Loose paint is removed and plants growing on the walls are removed as well. The walls should be as clean as possible to receive the coat of render. This is a time consuming process and should be done carefully.

Rendering is usually carried out in proper weather conditions. If it’s raining, the render might wash off. So make sure that you get the process done during proper weather conditions.

The render which is then applied forms a solid, strong and resilient surface which helps keep the inside walls safe from the elements. The sand used in the render is pretty sharp. This is because it’s meant to increase the strength of the render.
